Kuka KR C4 extended

This message indicates that the device is in an operational and healthy state. It is a status message rather than a fault.

The device has detected an internal error. This indicates a component or software malfunction within the KPP or KSP module for a specific axis.

The axis is overloaded, indicated by the IxT (Current x Time) monitoring function. This fault suggests that the mean continuous current is too high, potentially leading to overheating and damage to the motor or drive.

An overcurrent condition, specifically a ground fault, has occurred in the power unit of the KPP or KSP module for a specific axis. This indicates insulation breakdown or a direct short to ground in the motor or motor cabling.

A brief overcurrent has occurred that exceeds the maximum current rating of the KPP module. This is typically caused by a short-circuit or a sudden, excessive load.

The heat sink temperature on the KPP or KSP module for a specific axis is too high, indicating an overtemperature condition. This can lead to overheating and potential damage to the drive components if not addressed.

A failure has occurred in one or more motor phases connected to the KPP or KSP module for a specific axis. This indicates an open circuit or imbalance in the motor power supply, preventing proper motor operation and potentially causing damage.

A communication error has occurred on the controller bus involving the KPP or KSP module for a specific axis. This indicates a disruption in data exchange, preventing the controller from properly commanding or monitoring the drive.

The EtherCAT master has received an unknown status flag from the KPP or KSP module for a specific axis, indicating a software error within the EtherCAT master. This suggests an unexpected communication state.

The KPP or KSP module for a specific axis is reporting an unknown device status. This indicates an unexpected operational state not recognized by the controller.

The KPP or KSP module for a specific axis has detected an internal hardware fault. This is a critical error indicating a component failure within the drive module.

A failure has occurred in one or more mains phases supplying the KPP or KSP module for a specific axis. This indicates a loss of input power, preventing the drive from operating.

The supply voltage to the KPP or KSP module for a specific axis has fallen below 300 V. This indicates an insufficient power supply, potentially causing erratic operation or complete shutdown.

An overvoltage condition occurred during the charging phase of the KPP or KSP module for a specific axis. This could be due to excessive mains voltage or an insufficient number of connected capacitance modules.

The KPP module has detected an error in the ballast circuit, which typically includes the brake resistor. This indicates an issue with the energy dissipation components, potentially leading to overvoltage conditions if braking energy cannot be properly absorbed.

The ballast circuit is experiencing a permanent overload, indicating that the braking energy being generated is consistently too high for the connected ballast resistor. This can lead to overheating and damage to the brake resistor and drive.

This message indicates that the device is in an operational and healthy state. It is a status message rather than a fault.

The KPP or KSP module for a specific axis has detected an internal error. This indicates a component or software malfunction within the drive module.

This fault indicates that an axis is overloaded, leading to the mean continuous current being too high. It can occur during start-up due to excessive program load or during operation due to system modifications, temperature influences, or excessive power demand. The risk is potential damage to the KPP/KSP power units or the axis motor due to sustained high current.

This fault indicates an overcurrent condition within the power unit, specifically identified as a ground fault. This means there is an unintended current path to ground, often through compromised insulation. This poses a risk of electrical shock, equipment damage, and system shutdown.

This fault signifies a brief but significant overcurrent exceeding the maximum current rating of the KPP, often indicative of a short-circuit condition. Such a fault can cause immediate damage to power electronics, motor windings, or associated cabling due to excessive current flow.

This fault indicates an overvoltage condition in the intermediate DC link circuit during operation. This typically occurs when regenerative energy from braking is not adequately dissipated or if the incoming mains voltage is too high. Sustained overvoltage can damage the DC bus capacitors and power semiconductors of the drive.

This fault indicates an undervoltage condition in the intermediate DC link circuit during operation. This usually points to issues with the incoming power supply or the drive's charging circuit. Persistent undervoltage can lead to unreliable drive operation and potential damage if the drive attempts to operate outside its specified voltage range.

The EtherCAT master has received an unknown status flag from the KPP or KSP module for a specific axis, indicating a software error within the EtherCAT master. This suggests an unexpected communication state.

The ballast circuit is experiencing a permanent overload, indicating that the braking energy being generated is consistently too high for the connected ballast resistor. This can lead to overheating and damage to the brake resistor and drive.

The intermediate circuit of the drive system has failed to charge. This indicates a problem with the DC link charging process, preventing the drive from powering up correctly.

This fault indicates that the intermediate DC link circuit failed to charge properly during power-up or initialization. This prevents the drive from starting or operating, pointing to a fundamental issue in the power supply path or the charging components.

The brake cable monitoring device has signaled a fault, such as a short-circuit, overcurrent, or a break in the connection. This fault affects all axes simultaneously, indicating a problem common to the braking system.

This fault indicates an issue detected by the brake cable monitoring device, signaling a short-circuit, overloading, or a break in the brake connection, or that no brake is connected. This compromises the safety function of the motor brake, potentially leading to uncontrolled axis movement or dropped loads.
